The correct order of reactivity of hydrogen halides with ethyl alcohol is

Options

  1. AHF > HCl > HBr > HI
  2. BHCl > HBr > HF > HI
  3. CHBr > HCl > HI > HF
  4. DHI > HBr > HCl > HF

Correct answer

D. HI > HBr > HCl > HF

Step-by-step solution

Among hydrogen halides, as the size of halide ion increases, its reactivity towards ethyl alcohol also increases. Thus, the order of reactivity of hydrogen halides is HI > HBr > HCl > HF
